Abstract: An optical communication system that includes terminals that operate with different, widely separated wavelengths in which a terminal in the system may be configured to function in both a first operational mode and in a second operational mode. For example, a terminal according to the techniques of this disclosure may communicate with full duplex communication by transmitting a first optical wavelength and receiving a second optical wavelength while in the first operational mode. The same terminal may be reconfigured to transmit the second optical wavelength and receive the first optical wavelength while in the second operational mode. In some examples, the terminal may be located in a spacecraft, such as an orbiting satellite or other vehicle, and may communicate with other terminals such as airborne terminals, terminals located at ground station on the Earth's surface, or with terminals located in other spacecraft.

Abstract: An optical system includes a plurality of internal apertures, a plurality of external optical assemblies and a telescope assembly positioned between the plurality of internal apertures and the plurality of external optical assemblies. Each internal aperture is operable to receive a corresponding aperture-specific optical signal. Each external optical assembly corresponds to one of the internal apertures, and each external optical assembly is operable to direct the aperture-specific optical signal of the corresponding internal aperture in a corresponding external direction. The external direction for each external optical assembly is independently controllable and the telescope assembly defines a shared optical train arranged to direct the aperture-specific optical signals between each internal aperture and the corresponding external optical assembly.

Abstract: An optical communication system which is tunable and polarization insensitive is provided herein. The optical communication system may comprise an optical bench coupling an optical transmit pathway and an optical receiving pathway to an external pathway. The optical bench includes a polarization insensitive optical circulator. The system may further include a tunable component positioned along the optical receiving pathway, and a controller coupled to the tunable component.

Abstract: An apparatus (100) for optical pointing is disclosed. The apparatus comprises a telescope (120, 122, 124, 126), a transmission prism (114) rotatably coupled to the telescope, and a rotatable mechanism (132, 136) operatively coupled to the telescope. The transmission prism is configured to rotate around a first rotation axis (116), and the rotatable mechanism is configured to rotate around a second rotation axis (144) that is different than the first rotation axis.
